Criticise local guesthouse for second time in Dublin seaside town (7)
I believe the answer is:
rubbish
'criticise' is the definition.
(thesaurus)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for rubbish that I've seen before include "make a scathing comment" , "Litter or nonsense" , "Trash - nonsense" , "Waste matter" , "Nonsense or refuse" .)
